There’s a pretty hardcore mod you can use to add eSata support to your AppleTV. This completely replaces the internal hard drive, and is NOT for the faint of heart!
The Apple Blog explains how to expand Wake On Demand support under OS X 10.6. Sounds useful.
rEFIt is a boot menu for EFI-based Intel Macs. Might be interesting.
Here’s a thread on Webmaster World with some interesting changes to the .htaccess rules that ship with WordPress that supposedly really speed up site loading times. Might be worth checking out; I wonder if a WP Trac ticket exists for this?
Here’s a very detailed guide and install scripts on installing from a full retail OS X 10.5.8 DVD on a Gigabyte GA-EX58-UD5 Core i7 motherboard. Hackintosh, anyone?
The EFi-X™ Users Forums provide a place for former users of the EFi-X hardware dongle to congregate and keep their Mac OS X “hackintosh” systems running without the stupid thing. Useful for general OS X hackintosh information as well.
SlipCover creates very nice icons, targeted at media files, by merging an image (say, a movie poster) with a template (such as a DVD case). Very nice results, freeware, and extensible. Cool, Mac OS X only.

Ninite lets you set up multiple Windows applications at one time. Useful for installing the stuff I add to my work PCs.

AppleTV & More has an intriguing patchstick product that claims there is “no need to re-create your Patchstick and re-patch after an update.” It leverages a lot of AppleTV plugins and scripts via a menu-driven interface on the AppleTV itself. A lifetime subscription to all updates is $70; I wonder if this is worth it?
